The specific embodiment

As shown in Figure 1, this chaff grain sorter mainly comprise motor 15, be installed in reduction box 9 on the base 13, the air blast 3 of the big air quantity of low speed and be arranged on funnel 1, twin-stage shaking screen on the housing.

Funnel 1 is arranged on case top and is positioned at air drift top and communicates with the air channel, tilts to install a baffle plate 2 in the funnel 1, forms the outlet of narrow slit shape between baffle plate 2 and the funnel 1.Can make the chaff that has grain that falls by this outlet form the shape of holding court from behind a screen together like this, so that selection by winnowing.The shell dependence air blast support bar 17 of air blast 3 fixes with base 13 and is connected.

The end in air channel is a chaff discharging port 24, is blown out from this opening 24 by the wheat cavings of the no grain of wind.Can make the height of this chaff discharging port corresponding during production, the convenient chaff that blows out of collecting with the height of dress chaff transport vehicle.

Corresponding with the outlet of funnel 1, the twin-stage shaking screen is installed below the air channel, comprise three layers up and down, the scalping 26 of the superiors, middle dusting cover 25, the undermost dish 20 that connects.Scalping 26 can the grain after selection by winnowing sieve remove bulk foreign material such as stalk, stone, bulk earth, the above-mentioned foreign material that sift out are derived outside the housing by the bulk miscellaneous object outlet 23 that is connected in the scalping, grain behind the sieve can see through the sieve aperture of scalping 26 easily, falls on the dusting cover 25.

Dusting cover 25 can sieve dust and the fine sand littler than grain volume, so that can obtain cleaner grain.The grain that sifts out is derived outside the housing by grain-export 18.

Be positioned at connecing of bottom and coil particulates such as 20 dust of collecting and fine sand by outside the sand dust outlet 21 derivation housings.

Above-described scalping 26, dusting cover 25, to connect dish all be for 20 3 layers tilt to install, but incline direction is different.The three connects as one by support, is synchronized with the movement so that can realize.Described support comprises that four jiaos of every layer all are welded with a slide bar parallel with the body bottom surface, and this slide bar is derived outside the housing by the hole of body both sides, and slide bar can be free to slide in the hole.The two ends of each slide bar fuse by fixed connecting

rod

19 and 22 respectively outside machine, realize making scalping 26, dusting cover 25, connect dish 20 and can be synchronized with the movement.

A hinged movable rod 16 on the fixed connecting rod 19 wherein, the other end of this movable rod is hinged on the slide bar 10 of reduction box 9 outputs.The input belt wheel 11 of reduction box 9 connects the output wheel 14 of motor 15 by belt 12.The output pulley 8 of opposite side connects the wheel for inputting of air blast 3 on the reduction box 9 by belt 6.Realize scalping 26, dusting cover 25, connect dish 20 and air blast is all driven by reduction box 19 by same motor 15, make that structure is more simplified, compactness.

Shown in Fig. 2,3, three rotatable axles are arranged in the reducer shell 38 of reduction box 9, they are power shaft 35, jackshaft 36 and output shaft 37.Power shaft 35 and jackshaft 36 are major axis, and output shaft 37 is minor axises.Fixedly connected power shaft driving gear 28 on the power shaft 35; On the jackshaft 36 end fixedly connected counter shaft driven gear 29, the other end fixedly connected jackshaft drive pinion 30; On the output shaft 37 except fixedly connected output shaft driven gear 33, also fixedly connected crank 32, the end of this crank 32 fixedly connected a crank-pin 31, flexibly connecting connecting rod 34 on this crank-pin 31, the other end of this connecting rod 34 is flexibly connecting a pin 27, and this pin 27 is fixedly connected on the middle part of slide bar 10,

slide bar

10 and 35, the 36 vertical installations with 37 of three axles, be applied in reducer shell 38 tops, and can on reducer shell 38, horizontally slip.

The outside of reduction box 9 connects: fixedly connected reduction box power shaft belt pulley 11 on the reduction box power shaft 35, and fixedly connected reduction gearbox output shaft belt pulley 8 on the reduction gearbox output shaft 37, an end of slide bar 10 and movable connecting rod 16 are done the hinge type flexible connection.

When motor 15 energising rotations, the belt pulley 14 of motor 15 drives 11 rotations of reduction box power shaft belt pulley by belt 12, this belt pulley 11 drives power shaft 35 rotations of reduction box 9, the power shaft driving gear of fixing on the power shaft 35 of reduction box 9 28 rotates together, counter shaft driven gear 29 engagements in this power shaft driving gear 28 and the reducer shell 38 also drive its rotation, with its coaxial jackshaft drive pinion 30 rotations, with the output shaft driven gear 33 of jackshaft drive pinion 30 engagement with its rotation, drive output shaft 37 rotations and by reduction box output belt pulley 8 outputting powers.This belt pulley 8 makes air blast 3 rotations by the belt pulley on the belt 6 blower axles 4.

Blower shaft 4 two ends all are equipped with bearing, this bearing relies on the support of bearing 5 to fixedly connected with the shell of air blast 3, be fixedly connected with several blades 7 on the blower shaft 4, blade 7 rotates with blower shaft, and the wind of generation blows out by chaff discharging port by the chaff that the air channel will fall from the outlet of funnel 1.Grain remaining behind the sorting bran falls in the scalping 26.

Simultaneously, when output shaft 37 rotations, the crank 32, the crank-pin 31 that are fixed on the output shaft 37 rotate together, rotate with connecting rod 34 left ends of its flexible connection thereupon, it is reciprocating that the other end of this connecting rod 34 drives pin 27, because this pin 27 is fixedly connected on the middle part of slide bar 10, slide bar 10 also horizontally slips on reducer shell 38 thereupon.

Slide bar 10 drives scalping, dusting covers, connects that dish moves reciprocatingly by movable rod 16, the grain that falls screened, and final clean grain after obtaining screening by grain-export 18.

Wherein, bulk miscellaneous object outlet 23, grain-export 18, sand dust outlet 21 with scalping, dusting cover, connect dish and move back and forth, can prevent that outlet from blocking.
